Iimfuno ezintathu eziphambili zebhetri yokugcina amandla, ukhuseleko lolona lubalulekileyo
Ugcino lwamandla e-electrochemical luthathwa njengolona hlobo luphambili lokugcina amandla kwinkqubo yamandla yexesha elizayo, ibhetri kunye ne-PCS yeyona nto ibalulekileyo kunye nemiqobo kuluhlu lweshishini, imfuno ephambili ilele kukhuseleko oluphezulu, ubomi obude kunye neendleko eziphantsi. Phakathi kwazo, ukhuseleko luphambili. Ezinye iingcali zoshishino zithe, ngoku isityalo samandla okugcina amandla e-electrochemical siphuhla ngokukhawuleza, kodwa umba wokhuseleko yingxaki yophuhliso lwaso olukhulu, isityalo samandla okugcina amandla saseBeijing kunye neprojekthi yokugcina amandla yaseTesla Australia yokuqhuma kwayo, nayo imboni yokugcina amandla ivakalise isilumkiso.
Ngenxa yoku, iZimvo eziSikhokelo malunga nokuKhawulezisa uPhuhliso lweNdawo yokuGcina Amandla amatsha zibeka phambili ukusekwa kwemigangatho yetekhnoloji yokhuseleko kunye nenkqubo yolawulo, ukomeleza ulawulo lokhuseleko lomlilo, ukulandela ngokungqongqo umgaqo osisiseko wokhuseleko njengomgaqo osisiseko; kukhuseleko oluphezulu, iindleko eziphantsi, ukuthembeka okuphezulu, ubomi obude kunye nezinye iinkalo zenkqubela ende; ukomeleza ukhuseleko lophando lwetekhnoloji yokugcina amandla e-electrochemical njalo njalo. IKhomishini yoPhuhliso lweSizwe kunye noHlaziyo, iBhodi yeSizwe yaMandla ukuze iququzelele ukubhalwa kwe-"Interim Measures for the Safety Management of Electrochemical Energy Storage Stations (Draft)", nayo ibikho ngomhla wama-24 ku-Agasti kuluntu ukuze kuboniswene noluntu, ukomeleza ulawulo lokhuseleko lokugcina amandla.
Ukhuseleko oluphezulu, ubomi obude, ixabiso lebhetri ye-nickel-metal hydride
Idatha ye-China Battery Industry Association ibonisa ukuba i-nickel-metal hydride yombane ikhuselekile kakhulu, ubomi bomjikelo omde, i-electrode yayo entle eyenziwe ngama-nickel spheres, i-negative electrode esebenzayo ixhaswa yi-hydrogen storage alloy, yeyezinto ezizinzileyo, i-electrolyte yamanzi ineempawu ezilungileyo zokurhoxisa ilangatye, ayizukuqhuma kwaye itshise iingozi, uxinano lwamandla e-monomer yebhetri lufikelela kwi-140wh/kg; ubomi bomjikelo bufikelela kwi-3,000, ukutshaja okungaphantsi kunye nokukhupha umjikelo wesimo ukuya kuthi ga kwi-10,000 amaxesha nangaphezulu; ingasetyenziswa ngaphezu kwe-10,000 amaxesha; ingasetyenziswa ngaphezu kwe-10,000 amaxesha. Ngaphezu kwe-10,000 amaxesha; inokugcina izinga eliphezulu lokutshaja nokukhupha umbane kwindawo -40°C ~ 60°C. Ukuthengiswa kweemoto zeToyota HEV kwihlabathi liphela kufikelele kwi-18 yezigidi, kwaye kuxhotyiswe kakhulu ngeebhetri ze-nickel-metal hydride, akukho nanye imeko yeengozi zokutsha kwebhetri, ukhuseleko oluphezulu lwebhetri luqinisekisiwe ngokupheleleyo.
Ngaphezu koko, ukutshaja nokukhupha ibhetri kukuguqulwa kwamandla eekhemikhali kunye namandla ombane, ubushushu bunempembelelo enkulu kwindlela esebenza ngayo iikhemikhali. Izitishi zamandla zokugcina amandla zihlala ngaphandle, uninzi lweentlobo zeebhetri zichaphazeleka bubume kunye nobushushu, zinciphisa indawo yezitishi zamandla kwaye zenza buthathaka indima yokugcina amandla. Iibhetri ze-hydride ze-nickel-metal kwiqondo lobushushu eliphantsi kakhulu kunye nobushushu obuphezulu zisebenza kakuhle kwaye zitshaja kakuhle, ukuze indawo yesitishi samandla sokugcina amandla ibe bhetyebhetye ngakumbi, ilula, isebenze ngcono iyonke, eye yaba yinxalenye yayo kukhuphiswano lweendlela ezahlukeneyo zobuchwepheshe bebhetri "kunye namanqaku".
Enyanisweni, iibhetri ze-nickel-metal hydride kwisicelo semarike yokugcina amandla ziye zaba ngumzekelo. Ngo-2020, inkampani yokugcina amandla yebhetri ye-nickel-metal hydride iNilar yiBhanki yoTyalo-mali yaseYurophu ityale imali eyi-47 yezigidi zeerandi. Kuyaqondakala ukuba iNilar igxile ekudityanisweni nasekugcinweni kwamandla avuselelekayo, umbane omiyo kunye nezicelo zokutshaja izithuthi zombane, utyalo-mali lukukukhuthaza inkampani ukuba idityaniswe nebhetri kwiinkqubo zemarike zokuhlala, zorhwebo kunye nezoshishino kunye neenkqubo zemarike yegridi okanye yeziseko zophuhliso. Ngokutsho kweFrontiers in Polymer Science, iqela likaNjingalwazi uYi Cui kwiYunivesithi yaseStanford liphuhlise ibhetri ye-nickel-metal hydride (Ni-MH) yamandla amakhulu avuselelekayo kunye nezicelo zokugcina, kunye neenzuzo zobomi benkonzo obude kakhulu, akukho mngcipheko womlilo okanye ubushushu obubalekayo, akukho mfuneko yokugcinwa rhoqo, ukuziphatha okuhle kobushushu obuphantsi, kunye neendleko eziphantsi. Iqela likaCui liza kwakha iyunithi yovavanyo enomthamo wokugcina we-2 megawatts ngo-2021, kwaye liceba ukwandisa umthamo wayo ukuya kuma-20 amaxesha elo nani ngo-2022.
